AmeriGlo CLS Tritium Sight

Product Description

The AmeriGlo CLS Tritium Sight is a tritium night sight that fits Glock models 20, 21, 29, 30, 31, 32 and 36. It is listed under part number GL-119 and carries tritium on both the front and the rear.

Both sights use green tritium. That means a green dot up front and a green dot at the rear. Tritium glows on its own, so the sights stay visible when the room or the range gets dark. You do not have to shine a light on them first.

Who it suits

This sight is a good fit if you own one of the supported Glock models and want to replace the stock sights with something you can see in dim light. The model range covers several of the larger-frame and compact Glock pistols, so check your pistol against the list before you order. If your model is not on it, this sight is not the one for your gun.

It works for a home defense pistol, a carry gun, or a field and trail sidearm. Anyone who shoots in low light will notice the difference.

For gear, think about what goes with the pistol itself. A holster that clears the sights, a sight pusher or similar tool for installation, and a gunsmith if you would rather not do the swap yourself all pair well. Some owners also add a weapon light and train in the dark to get the most from the glow.
